Fig. REF  presents the application of video instance cloning based on video instance shadow detection, where we can successfully generate many cinematic video effects, ,
a man with a suitcase walks in a crowd flow.
To achieve this, we duplicate the paired shadow-object associations across frames from one sequence to another with the adjusted frame rate and motion blur, the final result is presented in Fig. REF  (c). In contrast, Fig. REF  (b) presents the result supported by Mask2Former [1]}, where it (i) fails to detect the instance in frames and also (ii) produces unrealistic effects without the associated shadows.
